Ixxviii PROCEEDINGS OF THE 



Serpyllum. In the course of some interesting remarks, Mr. 

 Somerville contrasted the parasitic plants of this genus, which 

 are almost leafless and destitute of chlorophyll, with the 

 Mistletoe, which possesses chlorophyll in its leaves, and may 

 therefore be regarded as only partially subsisting on its host. 

 He also contrasted the Broom rapes with the saprophytes, 

 another group of plants almost destitute of chlorophyll, but 

 deriving their nutriment from decaying vegetable matter and 

 not parasitic on living plants. It is interesting to observe that 

 the numerous parasites and saprophytes, which are characterized 

 by the absence of chlorophyll in their tissues, are not confined 

 to any one order, but are found in genera widely separated. 

 They all agree, however, in possessing a tubular or gamopetalous 

 flower. 



Mr. Somerville also exhibited specimens of Scutellaria minor, 

 L., from the shores of Loch Aylort, Inverness-shire, and Malaxis 

 pahtdosa, Sw., from Loch Maree, Ross-shire ; and after describing 

 the characteristic features of these plants, he enumerated the 

 various Scottish stations from whence they have been reported. 



Mr. R. Turner, V.P., showed a series of specimens of the 

 British Orobanclies ; also specimens of Hedysarum coronarium, 

 L., from the neighbourhood of Fiume, where the plant is 

 extensively cultivated for fodder. It is frequently found among 

 hay imported from the Continent.
